Light Echoes Solve Mystery of Tycho's Supernova
Ponca City, We love you writes "Powerful telescopes in Hawaii and Spain are using 'light echoes' from the original supernova explosion that have bounced off dust in the surrounding interstellar clouds to identify the precise type of supernova that Tycho Brahe saw 436 years ago. Although the echoed light from Tycho's supernova is around 20 billion times fainter than the original light observed in 1572, the team took identical images of the sky a few months apart and then digitally subtracted one from the other to find evidence for several sets of light echoes rippling across patches of dust in the northern Milky Way. 'Using light echoes in supernova remnants is time-travelling in a way, in that it allows us to go back hundreds of years to observe the first light from a supernova event. We got to relive a significant historical moment and see it as the famed astronomer Tycho Brahe did hundreds of years ago,' said Tomonori Usuda, of the Subaru Telescope in Hawaii. Tycho's original observations were particularly important as he immediately concluded that the new star, visible even by day, could not be closer than the Moon challenging the Aristotelian view of the cosmos, widely accepted since ancient times, which held that the sky beyond the Moon never changed." -
DIY Living Computer Battery
An anonymous reader writes "Talk about a living battery/pollution clean up/environmentally friendly battery, this seems to fit all the buzz words. Researchers at UMass reported in the journal Science about their sediment battery. 'Derek R. Lovley, UMass microbiologist and team leader, explained how the team used water and sediment from Boston Harbor, a collection of mason jars, ordinary electrical wiring and sterile graphite electrodes to determine the science behind the mechanics of a simple, sediment battery. Using Desulfuromonas acetoxidans (a Geobacter bacteria) the researchers were able to produce enough electrical current to power a lightbulb or a simple computer.'" The linked article is low on details - post 'em in the comments if you have more information on related projects. -
More On Phoenix Developer Consortium
Mike Bouma writes: "The Phoenix Developer Consortium is an developer organisation which is unhappy with the currently available computing solutions. John Chandler has written an article about a small start-up company which has been one of many developers to tap into the organisation for resource contacts and advice. "It allowed them to extend their resources and survive the perils of being a small company in a large world." If you are a similar minded developer and want to join and help others or yourself to take your Ideas2Reality contact Greenboy and include the following information (signing a NDA will be required). Among the members are important figures involved in the development of OSes like the Amiga DE, MorphOS and QNX RtP." -
New AmigaOS On Top Of Linux
tommy.tonteri@arcada.fi writes, "Amiga released (yet another) plan for the future at an Amiga-show in St. Louis on Sunday. They plan on making a new OS that will be hosted on top of (Red Hat) Linux. Amiga's partners in this new effort include Sun, RedHat and Corel. Yet another impressive-sounding plan, hope they will finally be able to pull this one off..." I of course will believe it when I see it.
